Treevenge (2008)

Foul-mouthed lumberjacks descend on a hillside of trees, cutting them down and trucking them to Christmas tree lots where families paw them, pick one out, take it home, stick it in a stand, and decorate it. The trees experience terror throughout the ordeal: we hear their squeals of pain when axed or sawn, the emotion of separation from family and friends, the fear of the unknown, and the despair they feel during the strange and bizarre rituals of families at Christmas. On Christmas morning, the trees strike back. Man, woman, child, and pet may be in for a grisly end.
